Here is Joe Error's information regarding setting up a network in the NCSX test cell.
From Joe's visit, he believes that we should have about 50 monuments installed in the floor and another 50 in the wall.
I reminded him about our platform and he said that it is always chore to preserve the network integrity. 
Sometimes you have to install additional monuments around one that must be covered.
 
Joe also offered that they could come up and layout where the monuments should be placed in a day or 2.
It will take us some time to core drill and install the monuments per his design.
(Larry and I were talking: As an alternative, we could probably just hilti drill holes and epoxy in a simpler monument.)
He said that they would be happy to come up and measure our network .
It would take 3 men 1 week to perform the effort - no charge to us (maybe just travel)
 
He also offered to train our people on the use of optical equipment. 
He said that while we have a good handle on the use of Leica and FARO, we would benefit greatly from basic optical course.
and indicated that any time in March would be a good time for him to train us.
He kept saying that we should learn to walk before we run (Optical before Leica) and optical techniques would provide good confirmation of our electronic measurements.
 
Thoughts?
 

Thanks,

Hi Mike, Tom,

 

We are in the process of responding to your requests as fast and accurately as we can.  Over the next day or so you will receive a number of correspondences from us.  This particular attachment consists of a set of blueprints for our floor monument.  We are recommending that you manufacture about fifty units.  The spider housing is a support fixture that holds the monument in place in the “cored hole” while the cement hardens.   

  

Our initial network design which you will be receiving shortly, calls for forty monuments to be installed to support the initial network campaign.  Obviously some monuments will probably be lost during the construction of your machine but nevertheless we deem them necessary in the initial phase to add strength and geometry to the network.

 

As a result you may wish to add additional monuments later, hence our recommendation for the purchase of fifty. We are also recommending the installation of forty wall monuments (different type).  They can be purchased as “off the shelf items” and will be covered in detail in our statement about the network coming soon. 

 

With regards to the price of these monuments, here in Oak Ridge, the cost of over 800 that we presently have installed averaged about $75.00 each.  Perhaps you can make them for less.  In the event that our cost is lower, we would be pleased to talk to our vendors on you behalf or purchase them here so long as it is legal and ORNL (S & A) can be reimbursed.    

 

We have also attached a brief power point presentation on the optical tooling equipment we recommend.  Keep in mind that with regards to optical tooling equipment, there is a specific method to our madness.  It is our desire to make optical tooling techniques interface seamlessly with common laser tracker practices. 

 

As stated above, other items will be following shortly including an estimate for our part in constructing your network and a statement expressing the statistical clarity of the final product.
